To all yio/icm t may concern.'

Ee it known that l, Jol-iN HENRY lirnnn, a citizen ot the United States, and a resident ot' Brooklyn, State of New York, have invented certain nen7 and useful Improvements in Tires, of which the Jr'ollowing is a specification.

rllhis invention refers to flexible tires 'for the Wheels of automobiles and other vehicles, and consists essentially in improvements in tires comprising a flexible metallic tube-like structure composed ot a multiplicity ot iiexible Wire strands tapered from the middle toward each end, which strands contorni to an arrangement thereot in curved arches Whose members will be in contact each With those adjacent thereto at all points from the tread surfaces ot' the tire around the contour of the tire to the rim, the opposite ends ot each strand or Wire being` some distance from each other, since each strand lies in a curved oblique position across the tire, and said ends oi' each strand being secured to the rim ot the Wheel by improved means. For this purpose, l have devised certain novel features oit construetion and combinations in the support of the Wires as Well as in the flexible tapered Wires. The invention, therefore, consists essentially in the construction, arrangement, and combination of parts, substantially as will be hereinafter described and then more fully pointed out in the claims.

ln the accompanying drawing illustrating my invention:

Figure l is a cross-section oit my improved tire;

Fig. 2 is a transverse section ol a modiiied 'iorm o'" the invention;

Fig. 3 is a partial plan vievv ot the rim ot the wheel showing one oit the wire strands in place and indicating` Where it is attached;

Figure l is a detail view ot one ot the tapered Wire strands;

Figure 5 is a transverse section ot my improvements applied to another form of Wheel rim;

Figure 6 shows a section of the supporting ring formed with .rolled edges; p

Figure 7 is a cross-section ot the same ring formed with folded and inclined edges.

Similar characters of reference designate corresponding parts throughout the different figures of the drawing.

Although the present means tor supporting and holding the tapered Wires in close Contact `with each ot1 er may be applied and related to many di'li'erent forms ot clincher and other rims, yet l have shown certain specimens ot mechanism for this purpose, but `Without the intention ot restricting the invention thereto, the same being offered merely by Way of illustration and explanation.

6 denotes the telloe ot' the Wheel, either ot Wood or any other material, to which the spolres are attached, which lead to the hub. Encircling this telloe is a metallic ring 5 having at one edge an inwardly inclined :tace and surrounded at its opposite edge With an independent bevel-taced ring "i", which parts are held in place by the bolts il and plates 8, said bolts passing through the telloe 6.'

rlhe clincher rim Which surrounds the bevel-faced rings 5 and has its inside tace provided with oppositely inclined circular faces 13 which come in Contact with thc eled faces of the rings 5 and 7, all as clearlj,7

indicated in Figures l and 2. This clincher rim is provided moreover at one edge with a flange l and is surrounded on its other edge With a detachable flange '2 which is held in place by a ring which is adapted to be seated in a grooved flange 3 on the ot the clincher rim opposite to the flange l. rlhe grooved flange 3 is inwardly curved as s iovvn, and the ring i which is seated therein is correspondingly curved and also has right-angled shoulder at 23, which receives a Correspondingly-shaped edge ot' the ring 2. This ring 2 is pressed against he ends oit the Wire strands 2O and locked in place by forcing the locking ring i to its seat between the groovcd 'Bange 3 and said flanged ring 9,. i

inside ot the clincher rim and concentric therewith, being seated between the flanges l and 2, is a circular supporting ring lO, near the opposite edges of which are provided pertorated strips l1 that are Welded to the plate l0, as shown in the drauf'ings,

so that a series ot openings is provided byv and in these strips l1 which Will receive the right-angled ends 24 oi the Wire strands 2O when the latter occupy the position shovvn by. the single strand 20 in Figure 3 and by the group ot Wire strands indicated in Figures l and 2. ln Figure l l have also indicated the ring l() as provided With central plates 14 ot greater or less size, which are welded thereto and Which 'formas it Were "strands, as shown in Figuiie 2.

nuts to receive the bolts l5 which screw thereintoand each bolt is passed throughl an opening 25 in the clincher rim so that the head 26 ofl said bolt may be in a recess between the inclined faces 13 olf theclincher rim and thus securely 'fastenthe ring l0 to the-clincher-Lrim and prevent any creeping` or displacemento'l" said ring l0 during the operation of the tire.

ln Figure?) I haveshown a portion of the rim and the wire-supporting ring together with ra single strand ol wire 20, it being understolod that the ytire is made up Vof a mul* tiplieity of these wires, as shown in Figures l and 2, which taper from the middle point toward 4:each end. A single strand laid out in the position that it occupies before being bent is shown in Fig. Ll. There it willbe noted thatthe wire is largest at the middle point and tapers therefrom toward each end. Near leach end it is bent vat an angle toy form a portion 20, the portion 20 at one end being inclined in a certain direction on `one side of the, axis of the wire Q0, and the portion 20* at the other end being inclined in the same direction but on the other side of the axis of the wire 20, while at each end of the angular'portions 20 there is a right-angled bend 24: which forms a part of proper length toengage transverse passages in the strips ll at the edge of the plate l0 or in the flangesv lat the edges of said plate. These wires 20 are placed close to each other', as shown in Figures l and 2,y and form an arch or crown construction for the tire, giving it a hollow ortube-like character, the tread portionbeing somewhat thicker or thinneraccordingly as the strands are made of'greater or less diameter at their middle portions. Thetread may be more or less liattened at this thick part, as isindicated in Figure l, depending, of course, upon the `material andvmode oit bending, or it may partake of the regular curvature of the Each strand, when it is put into place is not only bent into the form o'l a loop to carry it from one edge ofthe rim of the Ywheelto the `other edge, but it is also given a torsional twist. ltfwill be further noted that the bending of eachstrand is in a spiral. direction, the center-of the spiral being the center of the tube that forms the tire structure, as indicated a'tAin Figure 2. It will be noted that the vends of these tapered strands 2O are not opposite to each other, but are some distance apart, the distance amounting in many cases to akquarter or a third of the circumference they all `:form the spirally-wound envelope which encircles the periphery of the. wheel andI whosecircular axial line is the center of the curvature of the spiral bendings of the individual strands. it is essential kthat `these tapered strands should be held firmly vand strongly at their ends and not allowed to get out of place, but be kept all the time in close contact with each other' so that no foreign'substances such as sand, dirt, or moisture may be able to pass between them, there being no interstices or openings to permit anything of this kind. their the ends 2404i the strands are bent as describedand such ends 24; inserted in the orifices or openings in the edges of' the` supporting ring '10, the

`torsionalspiral twist of the strands will hold the ends in the ring 2O so that thereJ will be a very firm connection of the parts, which will not easily become disordered.

ln the assembling ofl the parts. if we assume that the ends 24 of the taperedwires.-

20 are lirstintroduced into the. passages in the strip ll alongside of the clincher flange l and the opposite ends 24 are ,left free until after these firstiends have beeninserted, it,y will then be necessary to introduce theseother ends one by one in the openings in the, other strip ll alongside the detachable flange 2. l/Vhen these ends are inserted one by one, the flange 2 will be pressed against them' to force them home, and at the same time the locking flange l will `be forced between the, flanged ring 2 and the clincher flange` 3, and when this locking ring l is pressed tightly` and firmly in position as shown in Figure l, the flanged ring 2 will be so held tightly against the ends of thetapered wires 2O that the latter will be effectually locked in position and the assemblingV ofl all the parts. throughout will thus be completed in la strong and working form, every part of the combination being tightly locked in place. It will bel understood, however, that the tor sional and spiral twisting of 'the wires 20v and the engagementof the ends thereof with the openings in the members ll on the ring l() will be sufficient to keep the wires in place without the pressure of the clincher or other flanges, inasmuch as the angular ends 20 carrying the bent ends Qlfwill, lwhen engaging the ring l0, have a strong pull rtoward each other, which will hold them in position and, therefore, itis possible to use the tire thus made up of ar supporting per-y forated ring 10 and a series of bent strands without any auxiliary means 'for keeping the strands in the ring, so that the combination of the supporting ring and the strands may be applied with Aany kind of rim, no matter what sort of flange it has and whether it isk demountable or detachable, or of any other construction. The rim, therefore, may be of any standard'or other type with the detachable flanges as shown, or for no-rim cut tire beads, or otherwise. n

ln Figure 2 I have shown a slight lmodi-fication in the construction Vofsonie of the llO parts for here instead of welding separate strips l1 to the edges of the ring 10 for the purpose of providing openings to receive the ends 2a of the tapered wires 20, I simply bend the edges of the plate l0 at right angles to provide flanges 12 and perforate these iianges to furnish openings to receive the ends 24 of the tapered wires. This is a simple and practical construction which will be found to be successful in operation. Also, with this modification instead of welding plate 14C to the ring l0 and using a bolt 15, I simply use a strap 16 which may be welded at one end to the plate 10 and which is provided with a projection 27 engaging the opening 25 in the clincher rim, and provided or not as may be desired, with a nut 28 on the screw threaded inner end of said proj ection 27 but obviously these details may vary within wide limits, and I can utilize any kind of a device for preventing creeping of the parts with the same succ-ess.

In Figure 5 I show a still further modication, presenting this time a different kind of rim, the same being a clincher 30 with outwardly curved side flanges 3l against which the strands 20 lie closely, having their ends 24, as before in Figure 2, engaging perforations in the bent flanges l2 of the ring l0. These outwardly curved flanges 3l will be found preferable to the rim shown in Figure l having the curved flanges l and 2 for many purposes, and I simply show this rim as another example. Furthermore, in Figure 6 I indicate another form of the supporting ring lwhich is here shown as a member 32 having the edge thereof rolled or spun at 33 with one or more bends so as to make circumferential beads at the edges, this being a. convenient method of manufacture and said beads when so formed being drilled with the necessary series of perforations 34: for the reception of the ends 24 of the wires 20. In Figure 7 I show a still further modiication, the supporting ring 85 being bent at the edges with inwardly-inclined bends 36, which are doubled back on themselves at 37 to provide flanges which are also perforated at 38.

Many changes in the precise construction and arrangement of the parts may obviously be made within the limits of the invention, and I donot wish to be confined to what I have here portrayed and described as there are so many changes which can be easily made therein and which I desire to reserve the right to make.

Having thus described my invention, what I claim as new and desire to secure by Iletters Patent is:

l. In a tire, the combination of a multiplicity of resilient double-tapered wires closely associated with each other, and each having a torsional spiral twist whose center is the center of the tire, and an auxiliary ring having perforated edges to provide anchoring means for holding the bent ends of said tapered wires.

2. In a tire, the combination of a series of tapered wires adapted to be torsionally and spirally bent from one edge of the tire to the other in the form of a series of crowns that are closely associated with each other so as to constitute a flexible tubular tire, the center of the spiral twist being the center of Said tubular tire, and a supporting ring for vsaid wires having lateral fianges provided with a series of openings to receive the bent ends of the tapered wires.

3. In a tire, the combination of a multiplicity of resilient double-tapered wires closely associated with each other, and each having a torsional spiral twist whose center is the center of the tire and means for keeping the ends of said wires in position, the opposite ends of they same strand being circumferentially distant from each other.

il. In a tire, the combination of a plurality of tapered wires forming a series of arches constituting the tread, each having a torsional spiral twist whose centery is the center of the tire, and a ring supporting said wires, the opposite ends of each strand being distant from each other a substantial portion of the circumference of the tire.

In witness whereof, I have signed my name to the foregoing specification.
